' SPECIFICATION forming part of Letters Patent No. 395,060, dated December 25, 1888.

Application filed February 4, 1887. Serial No. 226,543. (No model.)

To aZZ whom it may cancer/L:

Be it known that I, EMIL KASELOWSKY, of Berlin, Germany, have invented a new and Improved Air-Compressor, of which the following is a full, clear, and exact description.

The invention relates to that class of aircompressorsin which the air is first subjected to an initial pressure before entering the final compression-cylinder; and the object of the invention is to improve the construction of such compressors.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinalvertical sectional elevation of a compressor embodying my invention. Fig. 2 is a transverse vertical sectional elcvatitm of the same. Fig. 3 is a plan view. Fig. t is a sectional elevation otan i111- proved piston adapted to my air-compressor.

a u are two intake-cylinders, and in which the air receives its initial pressure.

b is the final. coinpression-cylinder. The pistons d d of the intake-cylinders a u and the piston Zof the final compression-cylinder, b, are mounted on separate piston-rods (Z d d, operated from one and the same cross-head, c, which cross-head c is operated by any convenient or desired power. By way of example I have shown the cross-head c as actuated by the steam-operated piston A in a cylinder, B, the said steam-piston being provided with two piston-rods, C, connected with the cross-head c. The said cross-head is also shown as provided with a slide for the wrist-pin of the crank-shaft D of the liy-wheel. To the shaft D, at the end opposite that carrying the dywheel, is connected the valy'e-rod of the slidevalve of the steam or other engine. The vtlywheel is provided with ratchet-teeth on its in- 1 ner side nearthe pcriphery, whereby, with the aid of thelever and dog-E F, the fly-wheel may 1 be started by hand should the engine stop on i the dead-center.

Any other suitable actuating mechanism 1 may be employed, and that shown forms no 1 part of the present invention.

The pistonsof the several air-cylindtn's operate simultaneously in the same direction.

The piston (Z of each initial compressioncylinder, a, is provided with a valve, 6, of the puppet variety, or of any other suitable construction, and in ,each cylinder a is arranged a valve, f, Fig. l,which communicates with a channel, g, at the side of the final compression-cylinder, 7), near the bottom, which passage g in turn communicates with the bottom end of a coiled pipe, 71, which extends around all the cylinders and commui'iicates at its upper end with the interior ot' the cylinder 1) through the medium of the inlet-valve k in the valve-box 17 at the top of. the said cylinder 1). An outlet-valve, on, is also fitted in the valve-box I, and its chamber communicates with the outlet-pipe '22-, which, like the pipe 71, is coiled around all the cylinders, and is connected with the outlet 0.

In operation the air is reccived in the dupli cate intake-cylinders a a, and, as the pistons in said cylinders are forced upward by the cross-head c or other power, the air passes through the suction-valves e to the rear of the piston, and upon the downward stroke the air in both cylinders a a receives its initial pressure, passes through the valves f to the passage or channel g, from thence to the pipe 71., and through the same to the final compression-cylinder, I), through the inlet-valve k. Upon. the next upward stroke of the pistons the air in the cylinder 1) receives its final pressure and passes through the outlet-valve m and the outlet-pipe n to the outlet 0, from whence it passes to a storage-cylinder or to a motor or other place of delivery, as may be desired.

To provide for the cooling of the air during and after the process of compression, I construct the apparatus with a water jacket or tank, 7), surrounding all the cylinders and the coiled pipe. The water-jacket p is preferably supplied with water from a feed-pump, q, or other source of supply, which. will insure a continual circulation of the water in the tank. To further aid the cooling of the air, I c0nf struct the cylinders with ribs 9, thereby in- M ore than two initial compression-cylinders may be provided for each final cmn n-essioncylinder, it: desired.

3y d nplicating' the initial ctnnpression'cyliuders a very great amount of air is forced into the final compressioncylindcr. The air, it will be observed, as it enters the cylinder I) from the cylinders a it acts on the face of the piston I, and thus acts to aid the downward stroke of the pistons, by which stroke, as previously explained, the cmnpression ot' the air in the cylinders a u, is effected. :ly my invention, also, the air is cooled in its j'iassag'e from the initial con'lpression-cylinder, which is a very desirable result, and in addition the air is cooled in its passage from the final compression-cylinder to the outlet.

The air in the final compression-cylindcr becomes very hot and has a temlency to inj uriously affect the piston.
